Question 1

Answer 1

Answer:

87.5% probability that it is NOT number 2.

Step-by-step explanation:

A probability is the number of desired outcomes divided by the number of total outcomes.

Desired outcomes:

Any ball not numbered 2. So 1,3,4,5,6,7,8. So 7 desired outcomes, which means that $D = 7$

Total outcomes:

All balls, which are 8. So $T = 8$

Probability:

$p = \frac{D}{T} = \frac{7}{8} = 0.875$

87.5% probability that it is NOT number 2.
